Edelbrock Victor Series Manifolds For Chevy LS

CHEVROLET LS1 V8VICTOR JR. LS1 (3500-7500 RPM)This high-rise single plane intake is capable of supporting up to 600 hp. The Victor Jr. LS1 accepts a square bore carburetor and includes an electronic timing module that picks up MAP, crank position, and cam position in order to drive the stock LS1 Coil-on-Plug ignition system. The module offers a choice of 6 built-in timing curves, each tailored for engine displacement, cam profiles, and fuel grades. The #29087 (manifold only) can be used on LS2 applications when matched with MSD's #6012 LS2 ignition controller (available through MSD® Performance). Includes a throttle bracket designed to work with 700R-4, 200R-4 and Turbo 350 transmissions. Most applications will require hood modification.

These new Super Victor intake manifolds are designed with 24% larger runners than our Victor Jr. #28457 along with a larger 4500 style plenum. The large plenum makes these intake manifolds ideal for nitrous and forced induction applications. They also feature tapered runners for increased flow at high rpm. Available with a 4150 or 4500 series carburetor flange. The Super Victor 4500 series manifolds can accommodate bores up 2.25". Super Victor #28215 and #28265 include machined fuel injector bosses. A carburetor mounted style throttle bracket is recommended.

CHEVROLET LS3 V8CROSS-RAM LS3 (1500-7000 RPM)Designed for Gen IV engines with LS3, L92 and L76 rectangular port cylinder heads. The Cross-Ram LS3 is ideal for anybody looking to combine great looks and outstanding performance between 1,500 - 7,000 rpm. The unique dual-plenum design features 13" long runners with flanges that will accept two, 90mm GM LS3 throttle bodies. The unique cross-ram dual-plenum design is ideal for twin turbo applications. When matched with high flowing air filters and inlet tubes, the dual-plenum system gives neck-snapping performance with plenty of options for engine builders and tuners. Dyno testing resulted with gains of 27 horsepower and 28 ft-lbs. of torque over a popular aftermarket manifold.

CHEVROLET GEN IV LS ENGINES V8VICTOR JR. L76/L92/LS3 (3500-7500 RPM)Designed for Gen IV LS heads (L76/L92/LS3 or similar GM Gen IV rectangle port heads), this manifold is for EFI or carbureted racing applications operating between 3500-7500 rpm. This manifold uses a standard square-bore carb flange that is compatible with both Edelbrock EFI intake elbows and single bore 90mm throttle body or four-barrel #4150 throttle bodies. L92 heads are only compatible with a 4.00" and larger bore diameters; smaller bores (including most 5.7L blocks) will require valve reliefs cut into the block. EFI manifold #28455 has additional bosses and machining that allow for the use of fuel injectors when combined with the #3638 fuel rail kit (sold separately). The L76, L92 and the LS3 all use the same cylinder head.
